Patented Sept. 25, 1951 AlbertW. Keight, Cumberland, 'Md., assignor to Celanese Corporation of America, a corporation of Delaware Application November 2, 1946, seriamohzousz Claims. (Cl. 2112: 124)" This invention relates to yarn package supports, and relates more particularly to a bobbin adapted to receive a large quantity; of yarn,

Yarn package supports commonly employed in the art generally comprise some form of bobbin upon which yarn windings are placed by suitable textile devices. Various types of bobbins have heretofore been employed depending upon the size and shape of the yarn package desired and upon the ultimate use for which the yarn package is intended. In the case of yarn packages which are to be employed in warping operations, the structure of the yarn package support is quite important since it must be capable of receiving a large quantity of yarn, and must also permit the yarn to be unwound at high speed without causing excessive or uneven yarn tensions. Prior to this invention headless or single flange bobbins were employed since the elimination of the flange at that end of the yarn package over which the yarn is drawn permits of a greatly increased Warping speed while at the same time avoiding any injury to the yarn due to abrasion or snagging on the flange. However, such packages suffer from the disadvantage that they permitted sloughing off. It is, accordingly, an important object of this invention to provide a yarn package support or bobbin which will be free from the foregoing and other disadvantages and which will be simple in construction and efflcient in use.

Other objects of this invention, together with certain details of construction and arrangement of parts, will appear from the following detailed description and drawing.

In the accompanying drawing, wherein a preferred embodiment of my invention is shown,

Figure 1 is a vertical cross-sectional view of my novel bobbin, and

Figure 2 is a bottom plan view of the bobbin.

Like reference numerals indicate like parts throughout both views of the drawing.

Referring now to the drawing for a detailed description of my novel bobbin, reference numeral 3 indicates the barrel of the bobbin which is preferably of wood but may also be made of any other suitable material such as fiber, metal or metal alloy. The extremities of the bobbin are reduced in cross-section to form seats 4 having shoulders 5. The seats 4 are adapted to receive coneshaped sections or skirts, the upper one of which is designated by reference numeral 6 and the lower one by reference 1. These skirts flareoutwardly away from the barrel 3.

The skirts 6 and 1 are molded to shape from any suitable material, preferably from a thermoplastic or thermo-setting synthetic resin. The skirts are. formed with an internal shoulderior projection 8 which is adapted to receive annular discs 9 and H. Drive screws l2 are employed for attaching the annular discs to the barrel 3 thus holding the skirts 6 and 1 in position on the barrel to form the bobbin structure. The arrangement of the barrel, the skirts and the annular discs is such that when assembled the discs 9 and H are spaced from the ends of the barrel 3 whereby any dimensional change in the skirts or barrel may be compensated for by tightening drive screws I2. To the free end of skirt 6 there is attached, as by drive screws l3, a flange I4 having a hand grip l5. Bottom skirt 1 is provided with a magazine wrap groove I6.

Advantageou results are obtained with a yarn package support of the design outlined above. For example, if a support is accidently dropped and a skirt, the flange or the barrel is damaged beyond further use, the damaged portion may readily be replaced: the entire support need not be scrapped. Moreover, the design of the support is such that sloughing off is substantially prevented.

It is to be understood that the foregoing detailed description is given merely by way of illustration and that many variations may be made therein without departing from the spirit of my invention.

Having described my invention, what I desire to secure by Letters Patent is:

1. A yarn package support comprising a barrel having reduced ends, a skirt seated in each of said reduced ends, said skirts being cone-shaped and flaring outwardly in a direction away from said ends of said barrel, a projection on the inside of each of said skirts, and means including an annular disc seated on said projection for holding each of said skirts on said barrel.

2. A yarn package support comprising a barrel having reduced ends, a skirt seated in each 01' said reduced ends, said skirts being cone-shaped and flaring outwardly in a direction away from said ends of said barrel, a projection on the inside of each of said skirts, and means including an annular disc seated on said projection for holding each of said skirts on said barrel, said annular disc being in a spaced relation to the ends of said barrel.

3. A yarn package support comprising a barrel having reduced ends, a skirt seated in each of said reduced ends, said skirts being cone-shaped and flaring outwardly in a direction away from said ends of said barrel, the skirt forming the upper end of the yarn package having a flange attached thereto and the skirt forming the bottom end of the yarn package having a magazine wrap, a projection on the inside of each of said skirts, and means including an annular disc seated on said projection for holding each of said skirts on said barrel.

4, A yarn package support comprising a wood en barrel having reduced ends, a molded skirt of synthetic resin seated in each of said reduced ends, said skirts being cone-shaped and "flaring outwardly in a direction away from said ends of said barrel, the skirt forming the upper end of the yarn package having a flange attached thereto and the skirt forming the bottom end of the yarn package having a magazine'wrap, a pro- I jection on the inside of each of said skirts, and means including an annular disc seated on said projection for holding each of said skirts on said barrel.

5. A yarn package support comprising a barrel having reduced ends, a' skirt seated in each of 4 said reduced ends, said skirts being cone-shaped and flaring outwardly in a direction away from said ends of said barrel, the skirt forming the upper end of the yarn package having a base angle of 13 and the skirt forming the bottom of the yarn package having a base angle of -14.
